ADC Working

Resources
The file single_ended.c, which is an ADC example created by TI. It was included with the Code Composer download.
I used this link because they also had multiple sensors that needed reading
http://e2e.ti.com/support/microcontrollers/stellaris_arm/f/471/t/200521.aspx

I used this piece specifically:

ADCSequenceStepConfigure(ADC0_BASE, 0, 0, ADC_CTL_TS);ADCSequenceStepConfigure(ADC0_BASE, 0, 1, ADC_CTL_CH0);ADCSequenceStepConfigure(ADC0_BASE, 0, 2, ADC_CTL_CH1);ADCSequenceStepConfigure(ADC0_BASE, 0, 3, ADC_CTL_CH2);ADCSequenceStepConfigure(ADC0_BASE, 0, 4, ADC_CTL_CH3);ADCSequenceStepConfigure(ADC0_BASE, 0, 5, ADC_CTL_CH8);ADCSequenceStepConfigure(ADC0_BASE, 0, 6, ADC_CTL_CH9 | ADC_CTL_IE | ADC_CTL_END);

I was accidentally putting "ADC_CTL_IE", which is an interrupt flag, on each configure step. So it would read the first voltage correctly, but the other ports were reading strange results.


Setting up PuTTY 
This is used in order to read the digital numbers.

Below are pictures of ADC working

The list below explains the voltages used
Sensor 1: 0.5V
Sensor 2: 1.0V
Sensor 3: 1.5V
Sensor 4: 2.0V
Sensor 5: 2.5V

Next, I put each one to 0V. For the last two samples, all of the power supplies were set to zero.

Lastly, I connected all the ports to the same power supply

Last official meeting for the semester

Monday (12/2/13) students are supposed to attend Friday classes, so if people are able I would like to have an unofficial meeting that day.

We discussed maze mapping and what the different types of data that will need to be stored.

My friend, Brad Berger, he was pursuing a computer science degree for about 2.5 years and I've started to bother him about maze solving pseudo code. Below is a link to my notes about his recursion function:

Picture Time

George soldered the motor's wires sorter and made them very professional looking.

Here's a picture of the washer (silver part in red box), so now the bolts do not rub against the green wheels.
